Under the Bronco system, the three guys that need to know the most about what's happening on the offense are the QB, the LT and the TE. They are looking for smart athletic TEs--yeah they want them to be able to catch the ball to spread the offense, but mostly they want them in the right place at the right time and be totally committed to the block, even if they are way outmatched.
The TE coach is all about saying that the best TE in the league is not the one that has the most catches. The best TE is the one that enables the offense to work better by doing lots of the dirty work on offense and route running in the right place and time.
The more Bronco disciples they get on the team or coaching the team, the faster they can impliment the system and educate the new guys about it.
(And given that Smith for the GM candidate could do a great job of getting Bronco style players, that I would think, would make him a no brainer unless he is odd in some way. Remember how Cass struggled some to find 3-4 guys because he wasn't used to finding them? I am guess Smith would know how to find a Bronco TE, RB, and Olinemen--positions where the Bronco's needs are a little quirkier than the rest of the league).
